Remove code duplication by using is_section_heading?
Handle sections whose title contains backticks

This occurs in git-fast-import
Handle double backticks before single backticks

This fixes rendering of the "fixup" section of git-fast-import,
see issue #208.
Allow the 'line' under a section heading to be arbitrarily long

This is consistent with how asciidoc seems to work, and fixes
rendering of the "filecopy" section of git-fast-import.
